For this project you will need a stick, some rubber bands, and a small piece of leather or some other type of fabric that is thick and strong. If you have guessed that we're going to make a slingshot, then you get a gold star. Let's do it.
All right then. First you need a stick. And it must have a V in it. If you are so unfortunate as to not live in the middle of the woods, perhaps you can find a suitable shrub in your neighbors flower bed, your wife's greenhouse, or maybe you can get one from a tree in the park down the road or at the town square. If you are going to procure a stick anywhere other than on your own property, it is best done under cover of darkness. Some people do not like to have fun and will not understand, so it is best to avoid them whenever possible.
Then you will need some rubber bands. I bought a whole package of them at Office Depot for $4.00 and something. This is enough rubber bands to make three or four decently powerful slingshots.
And here is a strip of leather. I bought a whole package of leather scraps at Hobby Lobby and this piece will work wonderfully. I guess if you have to, you could cut up someone's boots or a belt in order to get the leather off of it.
